Application filed July 16, 1908. Serial No. 443,925.

To all whom it may concern:

Be it known that I, JAMES WV. DUUGl-IERTY, I

a citizen of the United States, residing at McKeesport, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulStreet-Cleaning Machine, of which the following is a full, clear, andexact specification, reference being had to the accompanying drawings,in which Figure 1 is a side View of one form of ma chine embodying myinvention; Fig. 2 is an end elevation of the same; Fig. 3 is a sectionalview of the inlet pipe.

My invention has relation to street cleaning machines and is designed toprovide a simple and efiicient machine by which dirt and refuse may beremoved from the surface of streets.

The precise nature of my invention will be best understood by referenceto the accompanying drawings which will now be described, it beingpremised however, that various changes may be made in the details ofconstructlon and arrangement of the parts by those skilled in the artwithout departing from the spirit and scope of my invention as definedin the appended claims.

Referring first to the form of my invention shown in Figs. 1, 2 and 3,the numeral 2 designates a vehicle of any suitable character upon whichthe cleaning apparatus is mounted. Carried upon this vehicle is a dirtor refuse bin 3 into the rear end of which leads a suction collectorpipe 4 having a depending nozzle portion 5 adapted to travel in more orless close proximity to the surface of the street to be cleaned. Thisnozzle portion is elongated or widened transversely and is provided withan inlet opening 6. Secured to this nozzle portion is a loosening brush7 of any suitable character. The pipe 4.- is preferably supported andheld in proper position by suitable connection at 8 with the frame ofthe vehicle, or with the refuse bin 3. The lower end of the nozzleortion of the collector pipe is preferably ,ormed with a flexible joint9, as shown in Fig. 3. This joint may be formed in various ways. Asshown in Fig. 3 the nozzle portion 5 has a hollow spherical or ballportion 10 at its upper end which fits within a socket 11 ofcorresponding form and in which it is secured by the pivots 12 uponwhich the nozzle portion is or forward direction. The socket member 11is preferably carried by a short pipe secree to swing in a backward tion13 which telescopically engages the pipe 4 to permit the verticaladjustment of the nozzle. The loosening brush 7 is also preferablyconnected to the nozzle so as to be capable of vertical adjustment, asby means of the bolts 14 passing through the slots 15.

Secured to the telescoping pipe section 13 is a ring or collar 16 havingthe projecting trunnions 17 which are connected by links 18 with thelever 19 to which is attached an operating rod or bar 20 leading to ahand lever 21 adjacent to the drivers seat 22. By means of this leverand connections, the nozzle portion of the pipe can be raised andlowered and also swung upwardly out of the pathof obstructions or forany other desired purpose.

23 designates a motor of any suitable character, such as a gas engine,mounted on the vehicle 2 and connected by suitable gearing 24 with theshaft 25 of an air exhauster 26. This air exhauster'may be of anyapproved type, preferably a rotary pressure blower, having its inletconnected by a pipe 27 with the refuse bin 3.

The bin 3 is provided at its bottom with the discharge door 28controlled by the foot lever 29 and connections 30.

The operation will be readily understood. The brush 7 loosens the dirtand refuse in advance of the collecting nozzle 5 and such dirt orrubbish is drawn upwardly into the pipe 4 and into the bin 3 by theaction of the air exhauster. Owing to the comparatively large area ofthe bin 3, the latter acts as a separator for the dirt and refuse whichis deposited in the bin without being drawn through the exhauster to anyappreciable extent.

For the purpose of assisting in the separation of the dirt and refusedrawn into the refuse bin, any suitable arrangement of baffling may beprovided within said box or bin in the path of the incom' material.

11 These battles are also illustrate; in dotted lines in Fig. 1.

It will be apparent that many changes can be made in the apparatuswithout departing from the spirit and scope of my invention. Thus it canbe mounted on any desired form of vehicle driven by any suitable power;suitable brushes, such as are common in streetsweeping machines may beattached to the apparatus for sweeping the dirt to a convenient positionfor entering the inlet or collector pipe; the arrangement? of bafliinwithin the refuse bin may be clianged an the details of construction andarrangement can be departed from m many respects.

I claim 1. In a street cleaning machine, a movable vehicle, a bin orreceptacle mounted thereon, an air exhauster connected to the bin orreceptacle, and a suction inlet pipe extending.

from the bin to a position near the surface to be cleaned, saidcollector pipe having a vertically telescoping section terminating in anozzle at its lower end, the nozzle portion bein connected to saidsection by a jointwhih permits forward and back movement of the nozzle;substantially as described.

2. In a street cleaning machine,,a'movable vehicle, a bin or receptaclemounted thereon, an air exhauster connected to the bin or receptacle,and a suction inlet pipe extending from the bin to a position near thesurface to be cleaned, said collector pipe having a verticallytelescoping section terminating in a nozzle at its lower end, the nozzleportion being connected to said section by a.joint which permits forwardand back movement of 'the nozzle, together with lever connections forraising and lowering the telescoping section; substantially asdescribed.

3. In a street cleaning machine, a movable vehicle, a bin or receptaclemounted thereon, an air exhauster connected to the bin or receptacle,and a suction inlet pipeextending from the bin to a position near thesurface to be cleaned, said collector pipe having a verticallytelescoping section terminating in a nozzle at its lower end, the nozzleportion being widened laterally at its lower end and connected to saidsection by a joint which permits forward and back movement of thenozzle; substantially as described.

4. In a street cleaning machine, a movable vehicle, a bin or receptaclemounted thereon, an air exhauster connected to the bin or receptacle,and a suction inlet pipe extending from the bin to a position near thesurface to be cleaned, said collector pipe having a verticallytelescoping section terminating in a nozzle at its lower end, the nozzleportion being connected to said section by a joint which permits forwardand back movement of the nozzle, together with a dirt loosening devicesecured to the nozzle at the front side of the same; substantially asdescribed.
